COMB-DABBING MECHANISM.

SPECIFICATION forming part of Letters Patent NO. 609,385, dated August16, 1898.

Application filed July 30,1896. Serial No. 601,019. (No model.)

To all whom it may concern:

Be it known that I, J OHN W. OLAEKsoN, of Worcester, county ofWorcester, State of Massachusetts, have invented an Improvement inComb-Dabbing Mechanism, of which the following description, inconnection with the accompanying drawings, is a'specifioation, likeletters on the drawings representing like parts.

This invention has for its object to improve the construction of themechanism for operating the dabbing-brushes of wool-combing machines,whereby repairs due to the wear of the parts may be readily made and thecost of construction of the parts he reduced.

Heretofore the eccentric for reciprocating thedabbingbrush has beenembraced by an eccentric-strap connected to the brush-carrier.

In this invention I have placed between the eccentric and parallel facesfixed to the carrier for the dabbing-brush two shoes having concavedfaces which rest on the eccentric at opposite points.

Figure l is a front elevation of a dabbingbrush at the rear of thedotted line a, Fig. 2; Fig. 2, a section in the line :20, Fig. 1;' andFig. 3 is a detail showing the carrier, eccentric, and shoes.

In the drawings, A represents part of the stationary frame of awool-combing machine. It supports a frame B, having suitable guidewaysfor the dabbing-brush carrier 0 and the shank D of the dabbing-brush D.v

The carrier 0 is shown as made of two members O O, adjustably connectedtogether by a bolt C said parts having, guides or offsets c 0, whoseadjacent faces are shown as grooved for the reception of the outer endsof two like shoes 01 (1, said shoes having each a concaved face to restagainst and partially embrace the usual eccentric c on the shaft 6,having a belt-pulley 6 whereby said shaft and eccentric may be rotatedto reciprocate the dabbing-brush. The member 0 rests flatwise againstthe member 0 and is slotted at c at its upper end for adjustmentdabbing-brush respectively,

on the clamping-bolt 0 being provided intermediate its ends with aheaded holdingstud 0 working in a slot 0 in the member 0.

The shank of the dabbing-brush is connected to the dabbing-brush carrierby the bolt 0 referred to, and in case of any wear of the shoes oreccentric the part 0 may be adj usted on the part 0 to compensate forit. This construction not only reduces the cost of the machine, but addsgreatly to its durability, for wear between the eccentric and the partsin contact with it may be readily compensated for.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

l. A dabbing-brush, its carrier, an eccentric for actuating them, andshoes to bear on said eccentric, said carrier being composed of twomembers, one being slotted to receive a bolt from the other, saidslotted member resting on and being adjustable on the other member, eachof said members having at one end anoffset, said shoes resting on saidoffsets, and having concave faces resting flatly against said eccentricand terminating short of each other, whereby said shoes may be movedtoward each other to compensate for wear by the adj ustmentof the saidtwo members of the carrier, substantially as described.

2. Aframe, a shaft journaled therein provided with an eccentric, adabbing-brush guided on said frame, a carrier therefor composed of twomembers, a bolt carried by one of said members, and the other member andthe shank of the dabbing-brush being adjustable on said bolt, each ofsaid members having-a guide at one end, supporting a shoe, said shoesbeing concave to rest on said ec centric, but only partly surroundingthe lat ter, substantially as described.

3. The carrier, composed of two members, extending longitudinally of andagainst each other, one having a clamping-bolt and the other beingadjustable thereon, a holdingstud guiding them in such adjustment, aneccentric to actuate the carrier, shoes between the eccentric andcarrier, oneon each memname to this specification in the presence of herof the latter, said shoes being capable of two subscribing witnesses.adjustment toward each other to take up i I wear, a dabbing-brushmounted on said car- JOHN OLARKSON' 5 rier, and means to adjust saidbrush thereon,

substantially as described.

In testimony whereof I have signed my Witnesses:

JUSTIN A. WARE, SAMUEL B. SCHOFIELD.
